TO ALL WI-IOM IT MAY GONOERN:

.Be it knownthat I, Louis BRUMnAcrI, of Reading, Pennsylvania, have invented an Improvement in Wool- Burring Machines; and Ido hereby declare the following to be a full, clear, and exact description of the saine. My invention consists of a receptacle, hinged to the frame, and arranged, in respect to the toothed roller and slatted roller ofa wool-barring machine, substantially 'as described hereafter, so that the said receptacle can be raised by the burrs as they are carried round with/tbe wool by thetoothed roller, but will fall before the burrs arel acted upon by the slatted roller, the receptacle being thus in a position to rcceivethe burrs 'forced from the wool by the slatted roller, and preventingthem from fallingon to thewool as it is being carried round by the toothed roller. The advantage of'my improvement is' not only the thorough removal of the burrs from thc wool, but the' reduction of the s'peed ofthe slotted rollcr,jas more fully explained hereafter. i

In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference being had vto the accompanying drawing, which forms a part of this specication, andi which- I I Figure 1 is a vertical section of my improved,woolburring machine,and

Figure f2 a plan`view.-

The side-frames A and A of the machine are 'connected together by suitable cross-bars a a, and the platform b. In the said side-frarnes the feed-rollers B and B are caused to turn in thedirection of their arrows, and therollers D and E in the direction of their arrows. The roller'D'is composed of a number of metal disks d, with teethon their peripheries, somewhat similar to those of circular saws, the disks having distance-pieces between them of such a diameteras to leave the teeth exposed, and the whole being Ysecured together, so as to form a substantial -toothed roller.

The roller E has a number of bars or slats, e, of metal, the outeredges'of which revolve very-closely to; but n ot in absolute contact with, theteeth of the roller D The above-describedV mechanism is similar to that of ordinary wool-burring' machines, the wool being fed over and in contact with the platformv b to the two rollers B andfB", after passing-between which it is seized by the teeth of the rollerD, which open and carry round the fibres of the wool and expose the burrs, and the latter being acted upon by the rapidly-revolving 4slatt'ed roller'E, are discharged into any suitable receptacle.

' In ordinary wool-barring machines, the discharge of the burrs from the wool is, for the'most part, dependent uponl the rapidity with whichthe'slatted roller-E revolves, but' even rapidity of revolution does not eiiectually preventvthe burrs from'striking the edge of the receptacle, which is -alwaysa short distance. above the fleece, and thence falling on to tbetoothed roller D, and becoming again entangled with the wool as itis being carried round by the same. f v

In orderto obviate this evil, I make use 'ci' a. receptacle o r trough, G, which is hinged ata* tothe .frames and A of the machine, the bottom, t, of the receptacle, at 'and near the front end of the same, being shaped toA conform to the toothed circumference of the roller D, with which it is nearly in contact, absolute contact being prevented by lugs z'z, secured to the frame, on whichA lugs the receptacle rests. i l The receptacle is almost balanced, the preponderance being infront, so that the front` edge rests upon the fleece, and in close contiguity with the teeth ofthe roller D at all times, excepting when a burr is carried round with the wool, in which case the burr slightly raises the front of the receptacle. The latter falls, however, the instant the'burr has passed it, and before it cau be struck by the slats of the revolving roller` E, so that the burr cannot 'strike thecdge ofthe receptacle, whichisalways' in'a position to receivothe burr, and prevent it from falling on to the wool carried round by the roller D. I i

By the use ofthe above-described improvement, therollerE may he reduced in speed, as' the effective dis posal of the burrs is not dependent upon its rapid revolution, but upon I'the self-adjusting receptacle Gr, which 'is always in a position to .catc h the burrs.

I claim as my invention, and desire to secure by Letters Patentl The receptacle G, arranged in respect tov the slotted and toothed rollers of a. wool-barring machine, s described, 'and so balanced that it will be raised by a burr c arried beneath it, und willfall with its edge in contact with the eece before the slotted roller strikes the burr, all a-s and fol: the purpose described.

In testimony whereof, I have aligned my name t'o this speciation in the 'presence of vtwo subsoribig witnesses.
